Brainstorming & desk photo
I have to say I really like this theme. So many game ideas, so much room for interpretation. 
So the idea I came up with is a sandbox strategy simulation where you are the god of a tiny world. (See how elegantly I put the theme into this sentence.) You can’t influence the world directly, you have to give the villagers resources and control the weather for the world to grow and flourish. (So my game will be very similar to Grow.)
And here is the obligatory desk photo:
